The goal of the project was to create an extension to Internet Explorer forStatens Tjänstepensionsverk (SPV) which would give the staff the experience ofSingle sign-on (SSO) to external web service providers as well as manage andupdate their Passwords in a secure manner. The survey focused on the providersPalasso, ProCompetence and Wera. The extension was created as a BrowserHelper Object (BHO) with C# in .NET. The solution was implemented as aCOM object in a DLL-file that was running in-process with the browser. Theprogram used a locally stored XML file containing URLs, usernames andencrypted Passwords to the providers.

Under de senaste åren har den mobila tekniken i stort sett helt gått över till smartphones. Smartphones är i princip mer datorer än telefoner, som vi alltid bär med oss och som innehåller allt mer känslig information. Detta medför att kraven på säkerheten kring enheten ökar. Detta arbete undersöker om det är möjligt att finna en ny metod att låta användaren autentisera sig på, som är säkrare än de som är vedertagna idag, men samtidigt har liknande nivå av användbarhet. Vår idé, som vi arbetar med under namnet Colour a Symbol, baseras på att kombinera symboler och färger i par.

As the companies of today are good at protecting themselves against external threats, but are having problems with internal threats, we focused on how information can be protected from ending up in the wrong hands. First and foremost to protect information from employees who might steal it and sell it to another company. Since the security investments needed are connected to the financial costs of implementing them we have tried to create a balance between the investments needed and the cost of implementing them. The different kinds of protection needed are first and foremost protection to make data less accessable, Passwords and traceability. While it is hard for us to estimate the amount of money a company lose by the hour when the production stands still, we have not been able to use any of the excising models to calculate the profit of installing countermeasures.

Today many different types of lock systems are used all over the world. Passwords, finger prints and magnetic strips are a few examples. When the key is a three dimensional object, lika a physical metal key, the security depends, in a high degree, on that you can?t copy the object without access to it. One approach to copying the object is photographing the object, and from these photographs create a copy.

För att minnas långa lösenord är det inte ovanligt att användare rekommenderas att skapa en mening som sedan sätts ihop till ett långt lösenord, en lösenordsfras.Informationsteoretiskt sett är dock ett språk väldigt begränsat och förutsägbart, varför enligt Shannons definition av informationsteori en språkriktig lösenordsfras bör vara relativt lätt att knäcka.Detta arbete riktar in sig på knäckning av språkriktiga lösenordsfraser, dels i syfte att avgöra i vilken grad det är tillrådligt att basera en lösenordspolicy på lösenordsfraser för skydd av data, dels för att allmänt tillgängliga effektiva metoder idag saknas för att knäcka så långa lösenord.Inom arbetet genererades fraser för vidare användning av tillgängliga knäckningsprogram, och språket i fraserna modelleras med hjälp av en Markov-process. I denna process byggs fraserna upp genom att det används antal observerade förekomster av följder av bokstäver eller ord i en källtext, så kallade n-gram, för att avgöra möjliga/troliga nästkommande bokstav/ord i fraserna.Arbetet visar att genom att skapa modeller över språket kan språkriktiga lösenordsfraser knäckas på ett praktiskt användbart sätt jämfört med uttömmande sökning..

Public WiFi networks is one of the dominant technologies for users to get public internet access. The problem is that the networks are designed for accessability rather than security ? a problem users seldom are aware of. Users who carelessly access WiFi networks may reveal sensitive information which, among other things, can lead to an identity theft. Previous research suggests that users must be educated and informed about the risks they incur, but not how this should be done.

Quickmatch is a company that recruits students to other companies that need temporary workers. Today all administration is done by hand, which is very time demanding and therefore inefficient. Employees send assignment reports by e-mail about the working hours and breaks to the administration office. Since these reports are handled manually, there is a great need for an automated system that makes the company more scalable.The purpose of this work was to solve the defined problem, i. e.

With the advance of the modern information society, the importance of reliable identity authentication has increased dramatically. Using biometrics as a means for verifying the identity of a person increases both the security and the convenience of the systems. By using yourself to verify your identity such risks as lost keys and misplaced Passwords are removed and by virtue of this, convenience is also increased. The most mature and well-developed biometric technique is fingerprint recognition. Fingerprints are unique for each individual and they do not change over time, which is very desirable in this application.
